SK Hynix has talked about GDDR6 memory that features speed which is double what you get with GDDR5. The company will be supplying this memory to a client and you don’t need to be a journalist to connect the dots and figure out that Nvidia is the client here. GDDR6 memory could be used in the upcoming Nvidia Volta GPUs.
This means that if you combine GDDR6 memory with the 384-bit memory interface then you will be able to get 768GB/s of memory bandwidth. This is almost double what the Titan Xp and 1080 Ti are capable of providing. This combination could give us a significant bump in performance.
We have heard reports that Nvidia Volta will be coming out before the year ends, if that is the case then it is highly unlikely that the upcoming GPUs will feature GDDR6 memory as it will be coming out in early 2018. If Volta indeed features this new memory type then this could mean that Nvidia Volta based GPUs will not come out before 2018.
We recently learned that AMD Vega based GPUs will compete with GTX 1080 Ti as well as the Titan Xp, this means that AMD means serious business. Vega uses HBM2 memory which is different as compared to GDDR6. We do not know which one will come on top. It should be interesting to see which memory type proves to be better.
I think that AMD Vega GPUs will have a better price as compared to the high-end Nvidia 10 series GPUs. This might make Vega a better option for users. However, this does not mean that it will be better from a performance point of view.
The upcoming couple of months should be very interesting. AMD vs Nvidia battle is on again and we are waiting to see how well AMD does against the big player.
Let us know which architecture you think will come out on top in the end.
